COLUMBIA GLACIER
261
Transit Readings. Transit readings from Stations A, B and C, Columbia Glacier, August 23-24, 1909, and July 6-11, 1910.
Station A is located on the western side of Columbia Bay on a rocky spur about one-half mile south of the glacier front. It is a stake driven in the ground two feet east of twin trees, both of which are blazed on the east side. This station is close to but not the same as photographic station G, see Map 6.
